Here procmail uses just INBOX folder, this error happens also to Sent
and Trash folders that are used just by dovecot.

Just got this with current hg and imaptest:
Error: IMAP(username): FETCH for mailbox Trash UID 215597 got too
little data: 469042 vs 470768

But I'm not using a new user. I'm using the usual test user without
deleting any mbox or index.

Maybe that UID got corrupted by a previous dovecot version.

Now I start testing with a clean user and I'll let you know if it happens again.
